Land-Rover Defender 110

After many months of work through the last year, I present you my new supercar: a Land-Rover Deffender (110 version).

Yes, for me it is a supercar, it is not a truck trial or a normal 4x4. Yes, I know, it is very high and square, but it has many advanced features and solutions, and for me it is enought to call it supercar.

Note: The number with the name means the wheelbase in inches, 110 in this case, it is the most used. But nowadays exist 90, 110 and 130 versions.

My history with this vehicle:

When I was a child, in my town, everyone used a Land-Rover Defender
(usually very old) to go to the countryside, mainly for the
agriculture.
It's a extraordinary cross-country car and nearly indestructible. That's the reason why it's very used all around the world.

Since then, I am a Land-Rover Defender fan (nowadays, I have two of them to use in my family's farm).

I tried to built it some years ago, but with the parts avaiable in that moment it wasn't possible...(because of the wheels mainly).

But, with the new Unimog tires was the perfect moment to built it definetly.

This model is made in 1:8.4 scale, thus remains in 28 studs wide, 65 of length and 29 of high (without roof).

It have 5+R speeds secuential gearbox, with auto clutch.
The mechanism disconnect the clutch, change the speed and connect it again, pushing only once the controller.
I know this is not realistic, but I you want to control the gearbox remotely, this is the only way to do it.

The speeds ratio

R - 2.08:1
1 - 1.67:1
2 - 1.25:1
3 - 1:1
4 - 1:1.33
5 - 1:1.67

Also it has 2-speeds transfer case:

High range - 1:1
Low range - 3:1

Finally it has RWD and AWD modes

The maximal speed in high range 5th speed is around 4 kph(2.5mph)

It has front and rear live axles with long-travel suspension.

Complete interior with working steering wheel(3.6 laps, as the original Defender) and gearbox speed indicator.

It uses 3 IR recievers and 7 PF motors:

- 2XL for drive
- M for the steering
- XL for main gearbox
- M for the brakes
- M for the tranfer case
- M for connect the AWD

Of course the 4-cylinder fake engine moves with the drive motors.

The steering system is based in the real live axles system, it not uses the typical rack.

It has disc brakes in all wheels. They are very powerfull, enought to stop the transmision.

Also you can disasembly the bodywork removing only 4 pins and the steering wheel, do it is very fast.

With the bodywork removed, you can remove 5 more pins and take out the complete powertrain.

does the separated powertrain includes the sequential gearbox??if yes it would e fantastic because it seems very smal to me and because of the shape it is easyer to put in a smaller car than the mini's

With many patience and imagination hahaha, all my cars are designed with that system. In a technic creation you can't use digital programs because you can't know if the connections and structure will be enough strong and reliable.

Ditto - just voted for this on Cuusoo. Absolutely awesome... I cannot believe the detail/accuracy/scale, and the engineering is incredible. I'd part with a few hundred notes for this model! Please list parts/instructions!!

are there downloadable instructions anywhere?? I really want to see detail on your 'traction mode' and the transfer-case...as well as the super compact 5-speed transmission-shifting device!! SOOOOOOOOOOOO AWESOME!!

this moc weighs over 3000 grams, has 9cm wheels, is driven by two XL motors and has a 1:1.67 gear ratio in 5th gear in the high range. i am working on a supercar that currently weighs less than 1000 grams, has 6cm wheels, has a 1:1.19 gear ratio in 6th gear and is also driven by two XL motors, yet the motors in this car seem fine when driving off-road, and the motors in my moc seem to be always strained even when driving on smooth floorboards. how did you do this?

I know it must be very difficult to document the full MOC, but if you have the time, could you please post a instructions as well as a part list for the basic functioning structure, including the gearbox and various motors, but not necessarily with the land rover bodywork. I know it must be extremely difficult, but many members of the community would really appreciate it.

its just a great car! I sell this cars in Switzerland and my son is a great Defender fan. has 2 Landys with remote control. now he found your beautiful car in the net and would like to have one....could you please send me some instructions? that would wunderful :-)micha.wiedemeier@bluewin.ch

Hi there Sheepo. Like the the model, in LEGO of all things. I am an avid LR fan, owned many in my time. The LR 90, 110, 130 range is fulltime 4x4, with a lockable differential in the centre transmission. When I have some money I may buy some instructions, for the LR 90 as I owned one (Converted to V8 auto).

hi there, i have bought the intructions and en finished it yesterday, i love how it works and how it looks, but i have one question, how have you managed the wiring around the transmission, because the wiring stops the transmission from working.

Hello Sheepo,It's wonderful piece of work. Congrats! I also have a real D110 TD5, and I realy love him. So, I just couldn't resist and I've to write you about one detail on Your nice model. Maybe you can swap the blinkers with possition lights on front mask. The blinkers are on real Defender below the position lights, and I think, it's very very typical on Defender. It could improve the real look of your fantastic model... What do you think? Nice day. :-)

Sheepo, do you use rechargable batteries for your models? If yes, what type do you use and how much mA do they have? I am looking for an alternative to comparable expensive batteries. Lego does not recommend anything regarding their PF motors besides their special PF-accu-block.

Very nice and useful information. Why not write a book about this particular subject. For today’s economic variation and be short of of opportunities, it actually will be a very hot topic. Thanks a lot

Sheepo I am looking for a gearbox for my Ferrari 250 GTO and I have 2 questions 1. can I adjust the ratios ? on these boxes and which gearbox out of this and the mustangs is A. smaller ? and B. more efficient ? -Caleb

I now wonder sheepo in the mustangs instructions is it easy to just build the gearbox and will its gearbox perhaps handle as well with pre-specified ratios when primarily powered by two RC Motors --Caleb
